  • Patent number: 6865985
    Abstract: A foldable panel supporter includes a supporting leg frame and a supporter joint, wherein the supporting leg frame includes a lower supporting frame and an upper connecting frame which includes a pair of L-shaped resilient connecting arms adapted for being inwardly and slightly pressed. The supporter joint has a folding channel provided thereon to receive the two connecting arms of the upper connecting frame, wherein the folding channel has two holding portions at two ends thereof and a retaining portion extending between the two holding portions. The retaining portion has a width narrower than the two holding portions, wherein each of the holding portions is shaped and sized to receive the connecting arms therein, wherein by slightly and inwardly pressing the resilient connecting arms to an extent that a distance between the resilient connecting arms is equal to the width of the retaining portion, the upper supporting frame is capable of sliding form one of the holding portion to another the holding portion.
